To all whom 't may concern:

Be it known that l, EARL G.VVATROUS, acitizen ot' the United States, residing at Chicago, in the county ot' Cook and State of lllinois, have invented certain new and useful Improvements in VVater-Closets, of which the following is a description, reference being had to the accompanying drawings, 'forming part of this specification.

My invention has for its object the provision of novel and improved means for flushing said closets, whereby they may be flushed more quickly, certainly, and thoroughly than in the constructions heretot'ore employed.

My invention is eq ually applicable to closets having a rearward discharge, as is commonly the case with what are known as prison-closets and to closets having downward discharge, as in the morecomnon and conventional forms of water-closets.

Figure 1 of the accompauying drawings shows my invention embodied in the former style of closet, while Fig. 2 shows it embodied in one of the latter styles.

The gist of my invention consists in the provision of a discharge-passage from the closetbowl of such a nature and the combination with it of a jet of such a character that upon admitting the water-supply to the closet the Water issuing from the jet will move the water through the discharge-passage in a sub stantially solid column or plug, and thereby entrain behind and Carry withit both the solid and liquid contents of the bowl and deliver them to the outlet from the closet.

In the accompanying drawings,A represents the closet-bowl, B the discharge-passage, and C the jet-opening through the bottom of the bowl and directed toward the mouth of the passage B. The water-supply is admitted to the closet at D, whencepart oi' it passes into the closet-rim E and thence through the small orifices of the latter to the interior of the closetbowl, While the remainder of the supply is led through the usual passage (not shown) formed in the wall of the closet to the passage F, formed in the bottom wall of the closet-bowl and leading to the jet C.

The middle portion of the passage B is contraeted, so as to present an enlarged and flaring inlet or mouth to said passage from the closet-bowl and facing the jet U, and the proportions and relations of the parts are such that the spreadiug jet ot' water issuing from the orifice C will enter the flaring mouth of the discharge-passage B and cause a substantially solid column or plug ot' water to move through such passage, thereby entraining and drawing behind and with it all the contents, both liquid and solid, oi' the closet-bowl and delivering them to the discharge-outlet of the closet, whether such outlet be a rearward one, as in Fig. 1 of the drawings, or a downward one, as in Fig. 2.

The exact proportions and relations of the parts are not material so long as they are such as to bring about the mode of operation and accom plish the results which I have described; but I have 'found that a discharge-passage B two and one-half inches in diameter at its contracted portion and 'From three to three and one-tourth inches in diameter at its fiarng mouth, in combination with a jet three-fourths of an inch in diameter and located as shown, work well in practice.

I have found that in such a closet constructed in accordance with my invention the fiushing action is so strong as to not only efficiently flush the closet of its usual liquid and solid contents, but to discharge from it any heavy foreign substances which may be dropped into it, such as pieces of stone or metal or objects formed from them thereby insuring the instant and thorough fiushing of the closet whenever the water-supply is admitted to it.

I am of course aware that it is common in siphon-jet closets to employ a jet in the bottom of the closet-bowl for the purpose of aiding the discharge 'from the closet bowl through the short leg of the siphon; but in such closets the formaton of a water-plug in the long leg of the siphon is relied upon to withdraw the water from the short leg of the siphon and closet-bowl and ettect the flushing of the latter, and I am not aware of any instance in which the short leg of the siphon or the upwa rd discharge-passage of the closet has been of such a nature or combined with a jet of such a character as to produce the mode of operation and accomplish the results of my improved closet.

As will be obvious from the foregoing my invention simpliies the Construction oi' water-closets, eliminates objections and annoyances incidental to the use of siphon-closets such as clogging ot' the siphon, fiooding of the IOO oloset upon oversupply of Water, &0.--and permits the convenient employment of elosets in positions and relations Where sphon and other closets having a downward disoharge cannot he employed.

Having thus fully described my invention, I claiml. In a water-closet bowl, the combination, With an Upward discharge-passage leading from the boWl and having a contracted portion and a flaring mouth portion, of a jet lo- &04,644
